Bakelites are
1 Rubber
2 Rayon
3 Resins
4 Plasticisers
Explanation:

Which of the following is a step-growth polymer
1 Polyisoprene
2 Polythene
3 Nylon
4 Polyacrylonitrile
Explanation:
(c) Step growth polymerization involves condensation reaction between two difunctional monomer to produce dimer which in turn, produce, tetramer and so on with the loss of simple molecules like \({H_2}O,\,\,N{H_3},\,HCl\) etc.

An example of chain growth polymer is
1 Nylon - \(66\)
2 Bakelite
3 Terylene
4 Teflon
Explanation:
Chain growth polymer is also known as addition polymer. A chain-growth polymer is a polymer that is formed when molecules of the same monomer or different monomers add together on a large scale to form the polymer.Out of the given polymers, Teflon is a chain-growth polymer as the molecules of tetrafluoroethylene (monomer) simply add together to form the polymer.
